  • Patent number: 7048701
    Abstract: A lie-down massager comprises a frame having an elongated top panel with an elongated opening, a rider below the top panel, a guide member movably engaged between the base frame and the rider to enable the rider to make a horizontal reciprocation relative to the frame, and a lifter moving vertically relative to the rider. A shaft is rotatably engaged to the rider and eccentrically connected to a cam so the shaft rotation generates an eccentric rotation of the cam defined by an inner disk, an outer ring, and ball bearings circularly provided between the inner and outer disks where an outer rim of the outer ring abuts to a bottom of the lifter so the shaft rotating further generates vertical reciprocation of the lifter relative to the rider by the eccentric rotation of the cam.
